A camera mount assembly for holding a camera or other perception sensor that may be fixed with respect to a ground plane and used for incremental angle measurement of the camera or other perception sensor in three axes, such that the precise spatial relationships of imaged objects with respect to the orientation/position of the camera or other perception sensor may be determined. A base structure of the camera mount assembly may be affixed to a fixed or moveable support structure and multiple leveling devices and/or laser devices are provided to establish a reliable reference relative to the ground plane. Thus, the exact orientation of the camera or other perception sensor in space may be determined frame to frame, such that the precise orientation of imaged objects with respect to the orientation/position of the camera or other perception sensor relative to the ground plane may be determined over time.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The camera mount assembly of claim 1, wherein the second rotational adjustment mechanism is coupled to the first rotational adjustment mechanism by an arm structure disposed at an angle to the first axis and the second axis.
3. The camera mount assembly of claim 1, wherein the third rotational adjustment mechanism is coupled to the second rotational adjustment mechanism by a planar structure disposed along the second axis perpendicular to the third axis.
4. The camera mount assembly of claim 3, wherein the planar structure defines an aperture disposed about the third axis in which at least a portion of the third rotational adjustment mechanism is disposed.
5. The camera mount assembly of claim 1, wherein the third rotational adjustment mechanism is disposed with respect to the first rotational adjustment mechanism such that the third axis intersects the first axis.
6. The camera mount assembly of claim 1, wherein the camera or other perception sensor is secured to the third rotational adjustment mechanism.
7. The camera mount assembly of claim 6, wherein the camera or other perception sensor is secured concentrically within the third rotational adjustment mechanism.
8. The camera mount assembly of claim 1, wherein the base structure comprises one or more of a leveling device and a laser device for establishing a predetermined orientation of the base structure with respect to a ground plane.
10. The method of claim 9, further comprising determining a distance between the camera or other perception sensor and the object of interest and determining a position of the object with respect to the orientation/position of the camera or other perception sensor.
11. The method of claim 9, further comprising determining a distance between the camera or other perception sensor and the ground plane and determining a height of the object with respect to the ground plane.
12. The method of claim 9, wherein the second rotational adjustment mechanism is coupled to the first rotational adjustment mechanism by an arm structure disposed at an angle to the first axis and the second axis.
13. The method of claim 9, wherein the third rotational adjustment mechanism is coupled to the second rotational adjustment mechanism by a planar structure disposed along the second axis perpendicular to the third axis.
14. The method of claim 9, wherein the third rotational adjustment mechanism is disposed with respect to the first rotational adjustment mechanism such that the third axis intersects the first axis.
15. The method of claim 9, wherein the camera or other perception sensor is secured to the third rotational adjustment mechanism.
16. The method of claim 9, wherein the base structure comprises one or more of a leveling device and a laser device for establishing a predetermined orientation of the base structure with respect to a ground plane.
18. The method of claim 17, wherein the driver assist or autonomous driving system executes a machine learning algorithm.
